its an 87 carb engine, 65,000 miles
it is building crankcase pressure and hence leaking/consuming oil {NO, NO blue smoke, No smoke at all}
this engine has the air pump and egr stuff still on it but I would love dearly to remove ALL of this JUNK!
The heads have some type of Port thing on the very back and appear to be connected to the air pump through a series of pipes and vacume controlled valves and such.
one question is, could this be the source of excessive crankcase pressure?
BTW this engine is in a 1987 coachmen class a motorhome.
Next question is, I smell gas in the crankcase {At least I think I do} This coach has an electric fuel pump so I know that the manuel fuel pump diaphram is NOT an issue. Although with key on {Engine NOT running} the pump never shuts off.
Would a fuel pressure regulator suffice to prevent excessive pressure on the needle and seat in the carb? { I surmise that IF there IS gas in the crankcase it has to be getting there by bypassing the Needle and seat.}
OR could it be that the powervalve has gone south? the engine runs extremely well other than it is a real thirsty bugger { kind of to be expected seeing how this coach is a 33 ft and the gears in the axel are pretty low.
BUT I thought id at least get 10 mpg, where im am only getting 5. { ID BE HAPPY WITH 8}
CAN I replace the intake manifold with an aluminum one that does NOT have the egr and air pump stuff?
Can I plug off those air ports on the very rear of the heads with no ill affects?
A lot of questions I know!
be patient with me
Thanks
